The async
keyword in Swift is used to mark a function that may suspend its execution to wait for an asynchronous operation to complete. When an async
function is called, the await
keyword is used to indicate that a suspension can occur at that line. This allows the CPU to yield to other tasks that have work to do while waiting for the asynchronous operation to finish.

Migrate your app to Swift 6
Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.
A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
